I have both the S&W 642 as well as Kel-Tec P3AT. Currently I daily carry a GLOCK 27 as well as the P3AT in the pocket, with the nifty Kel-Tec holder it came with. Resembles, something you'd have a PDA in, I've been told... Not the best way to draw, if needed, but it's always there with me.
Sincerely,
Timothy
